' TOBACCO PIPE Filed May 19, 1928 PatentedA .une 3, 1930 PASQUALE MANCUSI, OF Pl-IIIIIILAZDEIPHIA.,l Il?lilNNSYL'V'ANIAA TOBACCO rirn Application led May 19,

My invention relates to new and useful improvements in a tobacco pipe and has for an object to provide an improved device of this character in which any moisture or sal liva thattends to accumulate in the saine will flow into the recessed closure and be prevented from entering the smokers mouth when drawing on the pipe during smoking thereof. l

Another object of my invention is to construct a tobacco pipe in a novel manner to provide a circuitous passageway from the tobacco bowl to the pipe stem.

A further object of the invention is to so construct the pipe as to provide a moisture receiving chamber separated from the other chambers and passages except for a duct leading thereto. l Y. Astill further object of my invention is to provide a tobacco pipe consisting of a main pipe bowl opened from end to end and provided with a stem having a hole therethrough leading to the interior of the main bowl so as to form communication with a circuitous passageway produced bythe in-` sertion of a removable cup partition having portions of its walls spaced from the walls of the `main pipe bowl and also froma tobacco bowl removably mounted in the main pipe bowl andprojecting into the cup partition, said stem also having an inclined duct projecting downwardly from the hole in said stem and forming a communication with the interior of the main pipe bowl below the pipe stem hole and leading into a moisturechamber formed between the bottom of the cup partition and a recessed closure removably mounted in the bottom of 'the main pipe bowl.

VWith these ends `in view, Vthis invention consists in the details ofconstruction and combination of elements hereinafter set forth and then specifically designated by the claims.- Y

In order that those skilled in the art to which this invention appertains may understand how to use andmake the same, I will describe its construction in detail, referring by numerals Vto the accompanying drawings 192s. serial No; 279,070.

forming a part of this application, in which z-l Y,

Fig. 1, is a longitudinal sectional view of a pipe constructed in accordancewith my invention. i y n Fig. 2, is a similar view of the main pipe bowl.

Fig. 3, is a vertical sectional view of the tobacco bowl.

Fig. 4, is asimilar view of the cup partition.

Fig. 5, is a view similar to the others of the bottom closure.

Inv carrying out my invention as herein embodied, 6 represents the main pipe bowl having a vertical opening 7 therethrough from end to end as plainly shown in Fig. 2, and provided with a stem 8. The main pipe bowl is internallyy threaded at both its upper and lower ends as indicated by the numerals 9 and l0respectively. The stem is provided with a hole 11 running from a socket 12 into the opening 7 above the lower threads 10. A. mouth piece 13 is insertible in the socket. With an inclined duct '14 extending from any suitable part of the hole 11 or the socket 12 into'the opening 7 of the main pipe bowl at' a point belowthe point of communication of the inner end ofthe hole 11: with said opening 7 and at a suitable point intermediate the lower threads 10, is also provided the stem 8. The duct 14 is of greater cross-sectional area than the hole 11.

In the lower end ,of the main pipe bowl is removably insertedthe cup Vpartition 15- by means of its exterior threads 16 engaging with the lower threads l0 of the pipe bowl and the outside diameter ofrsaid cup partition is smaller than the interior diameter of the main pipebowl between the threaded parts thereof so that the side walls of said cup partition are spaced from the yside walls of the pipe bowl and provide part of a passageway in communication with the inner end of the hole 11. The bottom wall of this partition divides the opening through the pipebowl into upperand` lower chambers and said bottom wall ofthe cup partition is located at a point between the hole 11 and duct 14 so that said hole communicates with ico lll

the upper chamber and the duct 14 communicates with the lower chamber.

The lower end of the pipe bowl is normally closed by a removable bottom closure 17, Fig. 5, which has exterior threads 18 for engagement with the lower threads of the pipe bowl and is preferably provided with a flange 19 to seat against the lower end of the pipe bowl and assist in sealing the lower end of said pipe bowl. When the bottom closure is properly in place, its upper endV is spaced from the cup partition so that the inner end of the duct 14 is left uncovered whereby saliva or other accumulations of moisture may pass through the duct into the recess 20 formed in the bottom closure 17.

1n the upper end of the main pipe bowl is removably mounted the tobacco bowl 21l` Fig. 3, provided with exterior` threads 22 for engagement with the threads 9 at the upper endv of said pipe bowl and above the threaded part of the tobacco bowl is a flange 23 to seat upon the upper end of the pipe bowl while below the threaded portion is a reduced part 24, the exterior diameter of which is less than the interior diameter of the cup partition, thus forming. the other part of circuitous passage indicated by the numeral 25, the other part of said passage, as before explained, being the space between the side walls of the cup partition and the main pipe bowl.

The lower end of the tobacco bowl has one or more openings 26 therethrough to form a communication between the interior of said tobacco bowl and the innermost part of the circuitous passage 25 so that when the pipe is drawn on, air will pass into the tobacco bowl through the openings 26 then through the circuitons passage 25 then through the hole 11 and finally out through the mouth piece.

hen tobacco is being burned within the tobacco bowl, the smoke will follow the line of air passage above described and will be cooled to such an extent as to provide a pleasant smoke. Any saliva or spittle or any moisture accumulating or tending to accumulate in the passageways of the pipe when finally reaching the outer end of the duct 14, will pass down said duct into the recess 2O in the bottom closure and since said duct is of greater c ross sectional area than the holder 11, the moisture from the tobacco and the spittle can freely flow into the recess. As the moisture enters the recess, it will displace the air and cause said air to pass through the duct 14. Since there is no opening between the recess 2O and the exterior of the pipe except through said duct 14, and since the passage from the bowl to the stem is practically unobstructed, the draft upon the pipe will not cause any of the moisture in the recess 20 to be drawn back into the pipe stem or mouth piece so that an exceedingly dry smoke can be Of course I do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention what l claim as new and useful is 1. A tobacco pipe including a bowl open from end to end and having interior threads at both ends, a stem, a tobacco bowl having exterior threads for removably mounting it in the upper end of the pipe bowl, the lower portion of the tobacco bowl being spaced from the pipe bowl, a cup partition having exterior threads at its bottom end for removably mounting through the lower end of the pipe below with the bottom wall of said partition spaced between the lower end of the tobacco bowl and the lower end of the pipe bowl, the interior of said partition being of greater diameter than that portion of the tobacco bowl surrounded thereby and having a smaller exterior diameter thanthe interior diameter of the pipe bowl thereby providing a circuitons passage from the lower perforated part of the tobacco bowl to a hole through the stem, a recessed closure having exterior threads for removably mounting it in the lower end of the pipe bowl and spaced from the bottom wall of the partition to provide a communication between the recess in the closure and another hole in the pipe stem.

2. rl`he structure set forth in claim 6 wherein the hole leading to the space between the bottom wall of the partition and the pipe bowl closure is of greater diameter than the hole leading from the circuitous passageway.

3. A tobacco pipe including a bowl open from end to end, a stem, a tobacco bowl removably mounted in the upper end of the bowl being spaced from the pipe bowl, a cup partition removably mounted in the pipe bowl through the lower end of the latter and positioned to provide spaces between said partition and the lower end of the tobacco bowl and the lower end of the pipe bowl, the interior of said partition being of greater 'diameter than that portion of the tobacco bowl surrounded thereby and having a smaller exterior diameter than the interior diameter of the pipe bowl thereby providing a circuitous passage from the lower perforated part ofthe tobacco bowl to a hole through the stem, and a recessed closure removably mounted in the lower end of the pipe and spaced from the bottom wall of the partition to provide a communication between the recess in the closure and another hole in the pipe stem.

In testimony whereof I have hereunto affixed my signature.
